Emissions Reduction Services

Fuel & Emissions System Cleaning

The fuel system provides power to your engine. After about 4,000 to 5,000 miles of driving, dirt, varnishes and carbon deposits form in the fuel system, on the intake valves and in the combustion chamber. These buildups reduce performance, and left untreated, can lead to costly engine repairs. The Service is a multi-step process that cleans the fuel system, including injectors. The cleaning system removes fuel varnish build-up, intake valve and cylinder head deposits, lead, and harmful carbon deposits. It utilizes a unique cleaning solution that will not damage the vehicle's engine components.

Does your vehicle need a fuel & emissions cleaning?

Manufacturers have yet to include fuel & emissions cleaning in their maintenance schedules. However, a vehicle can lose up to 15% of its original efficiency after only 30,000 miles due to carbon buildup. For optimum performance and minimum emissions, most manufacturers of fuel and emissions system cleaners recommend the service be performed at least once a year, with a booster treatment used at every oil change.*Available at participating Grease Monkey™ locations.

PCV Valve & Breather Element Replacement

Enhance engine performance and help the environment

The PCV (positive crankcase ventilation) valve and breather element work together in the vehicle's emissions control system. The PCV valve regulates the flow of gases to the intake manifold. The breather element, or crankcase breather, keeps foreign particles from entering the crankcase. They work together to keep gases and vapors from being expelled through the exhaust, reducing vehicle emissions. The PCV valve and breather element keep your vehicle running cleaner and help reduce sludge and contaminant buildup. During the service the PCV valve and breather element are removed and inspected. If the mileage interval and/or condition indicates replacement, new components are installed.

Diesel exhaust fluid significantly reduces NOx emissions, known to be harmful to our health and the environment.

Diesel Exhaust Fluid Replacement

Maintain horsepower and help the environment

Diesel exhaust fluid is a mixture of high purity synthetic urea and purified water, used in Selective Catalytic Reduction (SCR) systems on diesel engines. SCR is a leading technology that meets the 2010 EPA mandate to reduce levels of oxides of nitrogen (NOx) emitted from diesel engines. SCR systems use diesel exhaust fluid and a catalytic converter to significantly reduce NOx emissions. Diesel exhaust fluid is a nontoxic, nonpolluting, nonhazardous and nonflammable solution. It is carried on board SCR-equipped vehicles in a designated tank. Small quantities of diesel exhaust fluid are injected into the exhaust stream to mix with exhaust gases to form harmless nitrogen and water.

For the SCR system to operate properly, the vehicle's diesel exhaust fluid level needs to be replenished periodically, like fuel, but not as often. Many manufacturers recommend that the diesel exhaust fluid tank be filled at the same time as the oil change service interval, but diesel exhaust fluid usage does vary by drive cycles and by vehicle.

Does your diesel exhaust fluid need to be replaced?

Warnings will display on the instrument panel when the diesel exhaust fluid level is getting low and should be refilled. You will lose noticeable horsepower if the diesel exhaust fluid level gets too low. Diesel exhaust fluid must be added to the designated tank to resume normal power. *Available at participating Grease Monkey™ locations.
